TWO POINT ELECTRIC CONTACT PRESSURE GAUGE


THEORY:

The oil pump systems are generally equipped with a traditional pressure switch which is used to drive or control the operation of pressure-driven machines, such as Plastic Injection Molding Machine. To set up the operational pressure points of the traditional pressure switch, an additional pressure gauge is used to indicate the required pressure, the adjusting process is very inconvenient and further more, the Pressure Switch itself is not accurate as well.  Accordingly, to improve the situation like this, WEIBROCK contact device manufacturer in Germany develops a whole new set of 3” contact device to replace the traditional pressure switches and provide a safer working condition other than the traditional ones.
